Tutorial  Updated

Downgrade to 6.2 with no NAND backup, get ReiNX back!

A lot of people seem confused on this subject. As was I about an hour ago. Thought i'd make a thread and (hopefully) help out a few people who are out of the loop or just plain can't resist the urge to update.

This thread may become irrelevant in the near future due to added 7.0 support
This should also help people interested in playing warez get their games and the ability to install NSP games back.
This guide assumes you are a ReiNX user who has updated their switch.

If you have updated to 7.0 as a ReiNX user you are either in the following two situations:
Situation 1:
Your switch cannot boot into a CFW due to having set up with ReiNX and not having 7.0 support

Situation 2:
You are using another CFW and cannot use any of your previously installed NSP games.

Follow this guide and get ReiNX back:

  1. Download the latest release of Atmosphere CFW
  2. Extract the .zip onto your SD
  3. Download ChoiDujourNX and put it on your SD
  4. Find Nintendo Switch FW 6.2.0 somewhere or extract it from a game. (more info on how to do that in the release thread)
  5. Put your firmware files on your SD card in a folder named 6.2 FW
  6. Download hbl.nsp and put it in the atmosphere folder on your SD
  7. Enter RCM and launch fusee-primary.bin from the Atmosphere github page in step 1
  8. Launch the HBL by entering the album
  9. Launch ChoiDujourNX
  10. Choose Folder 6.2 FW as your install source
  11. Wait on OFW 6.2 to install make sure to choose the exFAT option if you have an exFAT formatted SD card
  12. Your switch should reboot into atmosphere, or be off at this point.
  13. Make sure your switch is on FW 6.2 if it is powered on.
  14. Turn off the switch and enter RCM and launch ReiNX.bin (which you should have from your previous install)
Enjoy! And don't update this time! A good tip is to keep your switch in Airplane mode so that the update does not auto download.
ReiNX should work as intended at this point.

Hello, I have the same problem as anhminh, what do I do now, I can't go in Choidujour on the switch anymore because i can't simply boot.
Just in case to be sure that we did the same mistake, anhminh if you wait a lot of time after injecting the payload do you have an error like "go on the www*nintendo*com/error/etcetc" ?

Sorry if your card is fat 32 right now then you should boot into cfw if all files are correct

If your card is exfat and you didnt install exfat driver then you will not boot CFW

Turn off auto rcm off after downgrade if you want to boot OFW

  • a_username_that_isnt_cool @ a_username_that_isnt_cool:
    Is it piracy if it was released for free? Not in my opinion, but I also think it's not piracy if buying it isn't owning it, and it's not piracy if you can't buy it from the original creators anymore.
  • K3Nv2 @ K3Nv2:
    Free release can have loopholes where they still make money through ads
